Those in the EU who want Greece to leave the eurozone are playing with fire, country’s Finance Minister said, claiming that no “fence” could possibly exist that would protect the union from a domino effect should Greece or any other member leave.

“Anyone who toys with the idea of cutting off bits of the eurozone, hoping the rest will survive is playing with fire,” Yanis Varoufakis told La Sexta, a Spanish TV channel. In an interview, recorded 10 days ago but broadcast on Sunday, Varoufakis warned that those in the EU who think they have been “ring-fenced” from the Greek struggle are mistaken.

“Some claim that the rest of Europe has been ring-fenced from Greece and that the ECB has tools at its disposal to amputate Greece, if need be, cauterize the wound and allow the rest of eurozone to carry on,” Varoufakis said. “I very much doubt that that is the case. Not just because of Greece but for any part of the union.”
